The spin is that Biden still has exactly Obama's position that those who are married should have equal rights, but they don't necessarily support allowing those who aren't married to marry. Obama's moderate heroism is pretty lame.

"I believe we can keep the promise of our founders, the idea that if you’re willing to work hard, it doesn’t matter who you are or where you come from or what you look like or where you love. It doesn’t matter whether you’re black or white or Hispanic or Asian or Native American or young or old or rich or poor, able, disabled, gay or straight, you can make it here in America if you’re willing to try.-Obama

Because the idea of two consenting and responsible adults of the same sex marrying is SO stupid.

yes it is when it defies the meaning of the word.
